我不用 PHP 编写代码，但我有一个从网上下载的表单，它工作得很好：
我想做的是在这里添加一些代码，可以启动 JS 脚本，简单的警报框，说“谢谢您的表单已提交”。此 mailer.php 文件收到表单后。
<?php
if(isset($_POST['submit'])) {
$to = "[email protected] /cdn-cgi/l/email-protection";
$subject = "Form Tutorial";
$name_field = $_POST['name'];
$email_field = $_POST['email'];
$message = $_POST['message'];
$body = "From: $name_field\n E-Mail: $email_field\n Message:\n $message";
echo "Data has been submitted to $to!";
mail($to, $subject, $body);
} else {
echo "blarg!";
}
?>
代替：
echo "Data has been submitted to $to!";
just
echo '<script type="text/javascript">alert("Data has been submitted to ' . $to . '");</script>';
